What is the use of starter relay?
A starter relay acts as an electrical circuit completer or circuit breaker in between the vehicle’s battery and the starter motor. It helps to boost the battery’s current so that not as great a current is required at ignition. The starter relay is sometimes, but not always, used in addition to a starter solenoid.
Which fuse will disable a car?

What causes a starter to go bad?

What is a starter relay and how does it work?
What is a Starter Relay? A starter relay is a small, electrical device found in the starting circuit of high-current motors. The relay is essentially a remote switch that controls a high-current circuit. In motor vehicles, a starter relay uses the small ignition switch current to close the much heavy-duty starter circuit.
What is the purpose of the fuse in the car box?
The fuse used in the car box is to limit the current and prevent the fire. A relay is a switching device that uses a small electrical current to control a much larger current in a second circuit. In other words, a relay routes power to a circuit or component when it is turned on.
What are the four basic functions of a motor starter?
A guide to the four basic functions of a motor starter 1 Disconnection and breaking. Any motor starter must be able to be disconnected from the mains and isolated to prevent a restart. 2 Short-circuit protection. The challenge with turning off electricity is that it likes to flow. 3 Overload protection. 4 Control.
Why does my starter not start when the car is engaged?
